Time for stopping process exceeded
Indramat · Indradrive
What does F7050 mean?
The axis failed to come to a complete stop within the allocated time after a safety-related stop command was issued. This indicates that the machine's deceleration was insufficient, or there was an uncontrolled movement during the stop, violating a safety stopping time requirement.
Common Causes
- Insufficient braking torque or worn mechanical brakes.
- Excessive inertia of the load for the configured stopping time.
- Incorrectly configured safety stopping time parameter.
- Faulty speed/position feedback preventing accurate monitoring of deceleration.
- Drive internal fault preventing effective braking.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Check the mechanical brakes (if present) for wear and proper function, ensuring adequate stopping torque.
- 2
Review the application's inertia and ensure the configured stopping time parameter (e.g., S-0-0XXX Safe Stopping Time) is realistic.
- 3
Adjust the drive's deceleration ramps and braking parameters to achieve faster stopping times if mechanically possible.
- 4
Verify the integrity and accuracy of the motor's speed and position feedback.
- 5
Ensure the drive's power section and braking chopper are functioning correctly to dissipate regenerative energy.
